【问题描述】：
我正在尝试检查检查的值以通过电子邮件发送，但它们是空白的。我正在使用引导验证代码。
我也尝试使用其中的每一个，但没有成功：
$accounting_services = !empty($_POST['accounting_services[]']) ? array() : $_POST['accounting_services[]'];
$accounting_services = !empty($_POST['accounting_services[]']) ? implode(' | ', $_POST['accounting_services[]'])
$accounting_services = nl2br(implode(',',$_POST['accounting_services[]'];
这是我的 HTML：
<div class="form-group">
<label><h4>WHAT ACCOUNTING SERVICES/FUNCTIONS ARE NEEDED?</h4>Mark as many as necessary)</label>
<div class="checkbox">
<label><input type="checkbox" name="accounting_services[]" value="Accounts Payable - Entering bills"/>Accounts Payable - Entering bills</label>
</div>
<div class="checkbox">
<label><input type="checkbox" name="Accounting_Services[]" value="Accounts Payable – Paying Bills w/ Approval"/>Accounts Payable – Paying Bills w/ Approval</label>
</div>
<div class="checkbox">
<label><input type="checkbox" name="Accounting_Services[]" value="Accounts Receivable – Invoicing clients"/>Accounts Receivable – Invoicing clients</label>
</div>
<div class="checkbox">
<label><input type="checkbox" name="Accounting_Services[]" value="Accounts Receivable – Entering receive payments and deposits"/>Accounts Receivable – Entering receive payments and deposits</label>
</div>
</div>
这是 PHP 代码：
<?php
// check if fields passed are empty
if(empty($_POST['name']) ||
empty($_POST['businessname']) ||
!filter_var($_POST['email'],FILTER_VALIDATE_EMAIL))
{
echo "No arguments Provided!";
return false;
}
if(isset($_POST['submit'])){//to run PHP script on submit
if(!empty($_POST['accounting_services'])){
foreach($_POST['accounting_services'] as $accountingselected){
echo $accountingselected."</br>";
}
}
}
$name = $_POST['name'];
$businessname = $_POST['businessname'];
$to = 'email@email.com';
$email_subject = "Contact form submitted by: $name from $businessname";
$email_body = "You have received a new message. \n\n".
" Here are the details:\n \n ".
"Name: $name \n ".
"Business Name: $businessname \n ".
"Accounting Services: $accountingselected \n".;
$headers = "From: $email_address\n";
$headers .= "Reply-To: $email_address";
mail($to,$email_subject,$email_body,$headers);
return true;
?>
【问题讨论】：
-
[]实际上在$_POST中生成了一个数组值，因此您不要在键中包含[]。您应该访问!empty($_POST['Accounting_Services'])，而不是!empty($_POST['accounting_services[]'])。要查看其内容和结构，请查看print_r($_POST);的输出。注意数组键也区分大小写，并且您的第一个复选框的大小写与其他复选框不同。这是我立即看到的。解决这些问题后，可能还会出现其他问题。 -
如果未选中复选框，则不会发送值。
